Hello , I need a wake-up call tomorrow morning .   Of course . When would you like the call ?   Actually , I need two calls , one at 7 and the other at 7 fifteen .   No problem . We'll give you both calls .   Do you know what , let's change the second call to 7 thirty .   No problem . Anything else , sir ?   Not at the moment , thank you .   Let me know if you do need anything .
